PBOTECTING-BASE FOB, FLUID-HOLDDG TANKS.

Patented Apr. 1, 1919.

Application led February 5, 1917. Serial No. 146,620.

T o all whom 'it may Concern:

Be it known that I, CHARLES R. Lamm, a citizen of the United States of America, residing at Detroit. in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Protecting` Bases for Fluid-Holding Tanks, of which the following is a specification, reference being had therein to the accompanying drawmgs.

The invent-ion relates to duid-holding tanks formed of sheet-metal, having more particular reference to constructions designed for use for holding liquid fuel in small furnaces, torches, etc. Itis the object of the invention to protect the tank from shocks and abrasions which might render the same leaky.

In the drawings:

Figure 1 is an elevation of a tank to which my improvement is applied;

Figs. 2, 3, 4 and 5 are sections showing modifications. .t

A is the tank, preferably comprisin a dome-shaped body portion formed o a drawn sheet-metal blank, and a. bottom portion B having a depending flange C engaglng an enlargement l) at the base of the body and retained by the return-bent flange E thereon. Tanks constructed in this manner have heretofore been extensively used, the seam between the anged bottom and body being soldered or otherwise rendered liquid-tight., and also constituting a support-y ing base for the tank. It has been found that tanks of this construction in the ordinary wear and tear of service frequently receive shocks or abrasions which cause a leak.

To avoid this, I have provided a protecting As shown in Fig. '2, the lower portion ofv the band F is iared outward, as indicated at I, forming a yieldable. resilient portion for receiving shocks. In Figs. f2, 3 and 5 the beaded edge G is formedwithout core, while in Figs. l and l a wire col-eis inserted within the bead as a further reinforcement. In Fig. 4 the band is provided with an inwardly-extending return-bent fiange J for supporting the tank, while the bead extends outward, and in Fig. 5 there is an inwardlyextending bead K for supporting the tank and an outwardly-extending bead Gr2 forming the supporting base. With all of the va- 'rious modifications the surrounding band will protect the base s0. as to avoid injury thereto.

For engaging the protecting band with the tank. it may be formed with a split therein, as indicated at L, and if desired the ends of the band'may be overlappedfand united by spot-welding or other means.

That I claim as my invention is:

1. The combination with a fluid-holding tank comprising a body portion enlarged at the base and a bottom portion with'v a depending {iange fitting wit-hin said enlarge.

ment and forming a vsealned connection therewith, of a protecting member formed of a. sheet-metal band surrounding said enlarged base portion, the upper end of said band being crimped over the shouldery at the upper end of said enlargement, and the base of saidV band being beaded and forming a support for the tank.

2. The combination with a fluid-holding tank, -comprising a bodv portion enlarged in diameter at the base thereof and abottom portion having a depending flange tting within said enlargement and seamed thereto, of a protecting member for said base, comprising a sheet-metal band surrounding said enlargement, the upper edge portion o said band being crimped to fit over the shoulder formed b v said enlargemenhand the lower `portion of said fband being beaded and ex-` tending beneath said depending flange to support the same. p

In ltestimony whereof I ailix my slgnature.

CHARLES R. LAMBERT;
